What we screen for in data engineers
- Data modelling, pipeline design and warehouse/lakehouse fundamentals
- Reliability: idempotency, data quality, observability and backfills
- Comfort across batch and streaming, and the trade-offs between them
- SQL and a production language (usually [Python](/skills/python-developers/)), plus modern data tooling
Every candidate is technically assessed by us, people who have done the job, before you spend a minute interviewing.
